Taking this into consideration, I wonder how Antonio Gomez did with his AmiMSX emulator because the SCC(+) chip emulation is pretty good. Anyway only 4 channels are emulated (instead of 5) and the PSG chip isn't emulated. But still...
You can load .HES PC Engine music rips into a sampler and rip the waveforms out directly for use in Protracker. This is how the same method "chipmods" used, using 16/32/64/128 byte sized waveform samples. (Depending on what octave range you wanted) Dunno why he'd need a new tracker really.
